Fig. 1 in Anticoccidial activity of the secondary metabolites in alpine plants frequently ingested by wild Japanese rock ptarmigans
Fig. 1. Direct effects of the natural components derived from alpine plants on E. tenella sporozoites. The viability of sporozoites treated with each natural component derived from alpine plants or lasalocid (positive control) with the viability of the DMSO-treated group set as 100%. The final concentration was 100 μM for the natural components, and 1 μM for lasalocid. SPZ: sporozoite; Las: lasalocid. Outliers were tested using Thompson's test (p <0.05), and the student's t-test was utilized to compare the data with the DMSO-treated group as a control (**p <0.01, ***p <0.001, ****p <0.0001).
Fig. 3 in Anticoccidial activity of the secondary metabolites in alpine plants frequently ingested by wild Japanese rock ptarmigans
Fig. 3. Confirmation of the active compounds using commercially available compounds and their efficacy. (A) The viability of sporozoites treated with each commercially available compound or lasalocid (positive control) was compared to the viability of the DMSO-treated group, which was set as 100%. The final concentration was 100 μM for the synthetic compounds, and 1 μM for lasalocid. SPZ: sporozoite, Las: lasalocid. The student's t-test was used for the comparisons (****p <0.0001) without outliers, as tested using Thompson's test (p <0.05). (B) The viability of sporozoites was determined at each concentration of the synthetic compounds that showed effectiveness at 100 μM. The half maximal inhibitory concentration (IC50) value was determined by approximating the curves obtained from the results.

The invasion rate of sporozoites treated with each natural component derived from alpine plants or lasalocid (positive control) with the viability of the DMSO-treated group set as 100%. Each compound was used at its maximum non-toxic concentration. Las: lasalocid. The student's t-test was utilized to compare the data with the DMSO-treated group as a control (**p <0.01, ***p <0.001, ****p <0.0001). Outliers were identified and removed using Thompson's test (p <0.05).

Hydrology and trophic flexibility structure alpine stream food webs in the Teton Range, Wyoming, USA
<p>Data and code necessary to replicate the findings from the manuscript titled "Hydrology and trophic flexibility structure alpine stream food webs in the Teton Range, Wyoming, USA".</p> <p><span>Abstract:</span><strong><span> </span></strong><span>Understanding biotic interactions and how they vary across habitats is important for assessing the vulnerability of communities to climate change. Receding glaciers in high mountain areas can lead to the hydrologic homogenization of streams and reduce habitat heterogeneity, which are predicted to drive declines in regional diversity and imperil endemic species. However, little is known about food web structure in alpine stream habitats, particularly among streams fed by different hydrologic sources (e.g., glaciers or snowfields). We used gut content and stable isotope analyses to characterize food web structure of alpine macroinvertebrate communities in streams fed by glaciers, subterranean ice, and seasonal snowpack in the Teton Range, Wyoming, USA. Specifically, we sought to: (1) assess community resource use among streams fed by different hydrologic sources; (2) explore how variability in resource use relates to feeding strategies; and (3) identify which environmental variables influenced resource use within communities. Average taxa diet differed among all hydrologic sources, and food webs in subterranean ice-fed streams were largely supported by the gold alga <em>Hydrurus</em>. This finding bolsters a hypothesis that streams fed by subterranean ice may provide key habitat for cold-water species under climate change by maintaining a longer growing season for this high-quality food resource. While a range of environmental variables associated with hydrologic source (e.g., stream temperature) were related to diet composition, hydrologic source categories explained the most variation in diet composition models. Less variable diets within versus among streams suggests high trophic flexibility, which was further supported by high levels of omnivory. This inherent trophic flexibility may bolster alpine stream communities against future changes in resource availability as the mountain cryosphere fades. Ultimately, our results expand understanding of the habitat requirements for imperiled alpine taxa while empowering predictions of their vulnerability under climate change.</span></p>

Data from: A de novo chromosome-level genome assembly of Coregonus sp. "Balchen": one representative of the Swiss Alpine whitefish radiation
<p>Salmonids are of particular interest to evolutionary biologists due to their incredible diversity of life-history strategies and the speed at which many salmonid species have diversified. In Switzerland alone, over 30 species of Alpine whitefish from the subfamily Coregoninae have evolved since the last glacial maximum, with species exhibiting a diverse range of morphological and behavioural phenotypes. This, combined with the whole genome duplication which occurred in the ancestor of all salmonids, makes the Alpine whitefish radiation a particularly interesting system in which to study the genetic basis of adaptation and speciation and the impacts of ploidy changes and subsequent rediploidization on genome evolution. Although well curated genome assemblies exist for many species within Salmonidae, genomic resources for the subfamily Coregoninae are lacking. To assemble a whitefish reference genome, we carried out PacBio sequencing from one wild-caught <i>Coregonus sp. "Balchen" </i>from Lake Thun to ~90x coverage. PacBio reads were assembled independently using three different assemblers, Falcon, Canu and wtdbg2 and subsequently scaffolded with additional Hi-C data. All three assemblies were highly contiguous, had strong synteny to a previously published <i>Coregonus</i>linkage map, and when mapping additional short-read data to each of the assemblies, coverage was fairly even across most chromosome-scale scaffolds. Here, we present the first <i>de novo</i>genome assembly for the Salmonid subfamily Coregoninae. The final 2.2 Gb wtdbg2 assembly included 40 scaffolds, an N50 of 51.9 Mb, and was 93.3% complete for BUSCOs. The assembly consisted of ~52% TEs and contained 44,525 genes.</p>
